,oi the'iUni ted;States, residing at Lancaster,

in tllwffiouiiitye.ofqjLanoaster and State of Pen? sylye'n-ia, have" "invented certein new Fife - hisiin ili rojnzr elsttesgptirt cularly to the constructheir ineinbers extended when the umbrella ans h rebv 'of wlrichtheygform a part is in use or to be pleeed perellelitoegich other in order to 0ccupyn small.:speeegwhen not in use.

The objectoi'lthe. present invention is to pro ride an umbrella rd) of the character reterred to capable) of ready folding or extension find: :tvhieh shall be combined with by the fct of raising an seen; in em; ;eX,tended position ready for use, and be retained in such position during use, presentinggthe appestrance of an ordinary umbrella rib. I

A further object is to provide an umbrella rib having the above characteristics wherein the parts may be quickly and easily folded by slight force exerted in the right direction;

With these objects in view the invention consists of anumbrelle rib having the gen eric and specific fen; ures of construction and arrangement of parts, substantially as hereinafter described and claimed.

The invention is illustrated in the accompanying drawing, in which;

Figure 1 is a side View of an umbrelle frame in which the novel form of ribs is. in-

f'member, the se ctizon being taken on line I In this drewi'n'gthe ribs are shown as corn ,7 posed'of two parts, 1 and 2. The part reig each-rib is of the. groove or paragontype and is intended, to be secured-to a notcli-' ring'3 of anumbrella' frame; The portion 1 of eachfrib has at the end opposite to'that'a't I which "it isettached to the notch-ring, pro- 55 jections 4 which extend into the channeior groove. "These proj-eetions'ms ybe formed in any suitable way, and they ere'prefe'rably I made by indenting the walls'of the part'of the rib as shown in Fig. 2. The portionEffie; of each rib'is 'pivotally connected to the pertion 1 thereof t shortd-is'tan'ce from the end having the projections or indentations. The portions 2 of the ribs may be either solid or of the peregon type. and they are of air-5' "'Ze to fit int-o and be entirely'inclosed by the grooves or chennels in the portions 1. Those parts 5 of the members 1 of-the located below the point of attachment of the members 2 are preferably formed to extend so slightly outwardly at an angle from the body of the member 1. v

The ends oi members 2 of the ribs when the ribs are extended, enter the groovesin the members 1 and are retained therein by frictional contact with inner faces of the grooves at the point where the projections or indentations are located. In order to give resiliency to the ends of the members 1. udjacent to the rejections or indentations, the so ends are pre erably slotted or notched to provide a bifurcated end between the parts of wb ih the ends of the members 2 are retained. Besides giving the requisite elusticity to the ends, the slots or notches prevent the accumulation of moisture fat the,

point of contact between the members of the ribs and prevent oxidation which might result in binding of the ports.

The ribs are connected by stretchers 6 to a 10G runner '7 arranged on the rod 8 and adapted to engage s rings 9 and 10 carried by the rod, in the usua way;

In the use of an umbrella containing ribs ofthe form described, when it is desired to put the umbrella into position for use, the umbrella is held in at position with the tip of the rod extending upward. This allows the ports of the ribs to which the cover is attached to drop into a position substantially in line with each other. When the runner is v moved upward on the rod the cover is put esult that the first brought into in dly bent ends of the upward movement of under slight tension portions 2 ofv the rib contact with the outw members I. As' the the runner is continued additional tension is scribed the umbrella presents the appearance latterwithoutdisconnecting the arts of the -it is only ribs. WVhen is desired .to fold t e umbrella necessary tofeicert a'slight force at the point of contact. between the members of the'ribsthus allowing them to be diSCOH-Q nected and to .beimove'dto-lie parallel to each other to occupy a small space. y a Having thus described my invention, what I claimfasnew, and desire to secure by Letters Patent is:'-
